REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3812 Adds a new package to maintain Platform Runtime Mechanism (PRM) support. This package is intended to include generic code that provides a common infrastructure to support PRM in firmware and a collection of sample PRM modules that demonstrate how to use the interfaces and other package resources to author a PRM module. The following initial headers are included in this commit: * Prm.h - Includes common content for PRM with no dependencies on other PRM header files. * PrmContextBuffer.h - Includes definitions for PRM context buffers. Context buffers are standardized structures that point to various resources available to a PRM handler during its execution. * PrmDataBuffer.h - Includes definitions for PRM data buffers. Within the context of PRM, these data buffers are composed of a generic header followed by a variable length blob of arbitrary data. * PrmExportDescriptor.h - Includes definitions for creating PRM export descriptors. A PRM export descriptor is a structure referenced in the export table of PRM module that contains PRM-specific metadata about the module. * PrmMmio.h - Includes definitions for describing MMIO ranges uses by PRM modules. * PrmModule.h - Includes definitions commonly used by PRM module authors. This file is provided to serve as a convenient include for PRM module authors. * PrmOsServices.h - Includes content specific to PRM OS services. OS Services will not planned to be present in the final version of PRM. The OS Services have been reduced to a simple debug print function. So this is currently planned to be a temporary file to support debugging during PRM development. Note: Modules built for the UEFI environment can be built by Visual Studio and non-Visual Studio toolchains. However, PRM modules are currently only supported on Visual Studio toolchain due to usage of export tables.
